At part of my Master's degree, I was required to choose a topic to research and write about. I chose to focus on a market analysis and design of brushless motor controllers. The design I developed was intended to aim for a market-gap in mid-power / high-power brushless motor controllers.
The design is theoretically capable of sustaining 500A continuous operation assuming a sufficient cooling system is implemented. A DSPIC33F microcontroller is the brains of the controller and allows for sensorless and sensored control. A wide operating range of 9V to 72V allows for a wide range of motors and applications. Multiple communications protocols are supported including RS232, RS485, CAN, USB, and PWM. Additionally, home-flags are supported to allow for robotics applications that are range limited or require absolute positioning.
